How do I add “subscribe via SMS” to my Facebook account?

From what I can tell there is no way to add the “subscribe via SMS” to one’s profile. This option is “turned on” by Facebook and should simply appear. Note that you will not see this option if you’re looking at your own profile. I would recommend asking a friend to log-in and go to your profile in order to see if the “Subscribe via SMS” option is present.
